Amacoil Unveils Spool Flange Sensing Options

Amacoil Inc., Aston, Pa., now offers reflective and non-reflective optical flange sensing systems
for use with Uhing traverse winding drives. The reflective version is used with spools that are
brightly colored or made of light-reflecting material. The non-reflective version may be used with
spools of any color or material. Both systems feature opto-sensors that detect the spool flanges
and signal a pneumatic or electronic switch to reverse the direction of the winding drive. The
systems enhance spooling accuracy and eliminate the need to adjust end stops when spools of
different widths are used. Amacoil stresses that with either system, spools must not be warped or
have damaged flanges.
